Copernicus Science Centre

This guide to the Copernicus Science Centre in Warsaw opens in 2006, years before the building existed, when a traveling roadshow called Experiment drew huge crowds to a science picnic on the Vistula riverbank, the gamble of Robert Firmhofer, tasked with building Poland's first science centre. The galleries now hold hundreds of hands-on exhibits, from a robotic theatre where machines hold conversations to a high-voltage demonstration, and a pendulum that quietly proves the earth is turning beneath your feet.
